To all whom it may concern;

Be it known that I, HERBERT VVILLIAM IZOD, a subject of the King of Great Britain, residing at Upper Norwood, Surrey, England, have invented new and useful Improvements in Apparatus for Oxygenating Air, of which the following is a spec fication.

This invention relates to the production of a combustible gaseous mixture for use in internal combustion engines or for burning with ordinary or other suitable burners or mantles for the production of heat or light, and particularly to the production of a combustible mixture whose calorific value is enhanced by the enrichingof the atmospheric air employed by means of oxygen.

According to this invention atmospheric air is passed over chemical substances which give up their oxygen and the resultant is passed through a carbureter of any suitable form.

By means of this invention the explosive, heating and lighting powers f the combustible mixture are considerably increased and therefore such combustible mixture is eminently suitable for use for manufacturing and commercial purposes, for cooking and for lighting. Owing to the calorific efliciency of he resultantgas the quantity of liquid hydrocarbon required to carburet a given quantity of combustible mixture is considerably reduced, thereby achieving an Further, hydrocarbons such as heavy liquid hydrocarbons can be employed which have hitherto been found to be unsatisfactory for carbureting air owing to their high percentage either of carbon or of incombustible elements.

The present invention may be carried into efiect by passing atmospheric air over the chemical substance in a dry state. This method may be carried out by passing atmospheric air through a vessel containing the chemical substances arranged in such manner that a large surface of the latter is exposed, and subsequently through a carbureter containing petrol or other liquid hydrocarbon.

Baffle plates, gauze screens and like devices may be employed and the chemical substances may be in the form of powder,

granules, cubes, balls or the like. A gauze screen should also be used to free the atmospheric air from dust and like impurities.

In cases where the mixture passes rapidly through the plant a trap may be provided in the form of a tank in which may be collected the free particles of liquid carried through the pipes by the excessive velocity of the mixture, and if desired, such trap may be so arranged that the liquid collected thereby may be returned to the carburetor. In order that this invention may be fully understood reference is to be had to the accompanying drawings which illustrate in sectional elevation the preferred form of apparatus for carrying out the same.

Atmospheric air to be carbureted is admitted through a pipe a into a vessel 7). In said vessel 7) and directly connected to the pipe a is a container for the chemical substances. The container comprises two cylinders of wire gauze c and (Z arranged concentrically between two rings 6, f which are of U section. The ring 6 is secured by means of a flanged screwed socket g to the pipe a, which projects into the cylinder (Z so that the air admitted by the pipe will pass into the interior of the cylinder (Z and the ring f is secured to a cross-member h, said member 71. and the flanged screwed socket 9 being tied together by rods The cross-member h is so arranged that the air in the interior of the cylinder (Z can pass out into the vessel 7). The chemical substances are arranged in the annular space between the cylinders 0 and cl and the air in passing through the cylinder clwill come into contact with said chemical substances which will give up oxygen thereto. Similarly, when the air has passed out through the bottom of the cylinder (Z into the vessel 5 it will again come into contact with the chemical substances through the gauze cylinder c.

It is to be understood that part of the air may pass directly through the gauze cylinders 0 and (1 instead of passing out at the bottom of the cylinder d. The vessel Z) is provided with an outlet pipe k at the top thereof and said pipe is connected to a pipe 70 which leads into a second vessel on containing petrol Or other liquid hydrocarbon. The

pipe 70 extends almost to the bottom of the vessel m and is provided with a number of small orifices 71. arranged below the level of the liquid in the vessel m. 0 is anoutlet pipe leading from said vessel m.

In cases where the velocity of the air through the plant is considerable, a trap is provided. Such a trap comprises a vessel 7) into which the pipe 0 extends on one side of a gauze screen 9, or a series of such screens and an out-let 7" from the top of the vessel 79 is provided on the other side of the screen 9. The outlet 0 or the outlet 1' as the case may be, is connected to a gasometer or otherwise as may be desired.

It is to be understood that any suitable form of carbureter may be employed in place of the vessel m and pipe 70.

The air may in some cases be dried and it is preferably heated and it may be forced or induced through the plant. The most convenient method is to drivenby a hot air engine and to pass the air to be treated through the cooling jacket of the engine so as to serve the twofold purpose of cooling the engine and heating the air before its admission to the vessel 6.

The oxygenating agents or materials em ployed may be varied in combination or quantity for different purposes as may be required, and such agents preferably comprise any of the alkaline peroxids such as the peroxids of sodium, barium, calcium, magnesium and the like, chlorate of potassium and permanganates of sodium and potassium. These agents may be employed in the proportions and combinations hereinafter set forth by way of example, but it is to be understood that any one or more of such agents may be used if desired.
